here is an email i got from joe at pacific saying that if i send him a video or a pic he'll put it on his website for me cool huh.
This code is typical to be in your pcm when you have program loaded, however it should not trigger your service engine soon light, and it will not cause any harm.....
enjoy the power, let me know how much power your truck makes and send me a photo of your truck on and off the dyno, maybe even a nice tire smoking burn out, and we will post them to our site with your dyno results... ...
thanks
again.

that's the p0602 ecm comm error code i've been asking about
it's been thrown with a p0336 crankshaft code they both come at the same time then the ecm error stays around and around forever can't clear it, it comes right back
